WINDOW-SCREEN.-

Speciflcation of Application filed July 5,

. struct a window screen and toso combine the same with the sash in connection" with which it operates that said screen will not interfere with the full closing ofthe sash or with the swinging ot' the same in the case ot' a swinging sash, will completely protect the opening formed when the sash is raised, but will only partly screen the sash when the same is lowered, and will not therefore, under the lattercircumstances, obstructthe view through the upper part of thd sash pane. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in Which- 1 Figure 1 is a sectional perspective view of part of a window frame, its sashes, and the screen operating in conjunction with the lower sash, showing the parts in the position assumed by them when said sash is lowered; Fig. 2 is a similar view showing the parts in t-he position assumed by them when 'the lower sash is raised, and Fig. 3 is a transverse sectional view on a larger scale than Figs. 1 and 2. 1 'i In Figs. 1 and 2 of the drawing, 1 represents part of the Window trams or easing, 2 the lower sash, and'3 the upper sash, which are guided in the window frame in the usual way. The screen iscomposed of-two sections 4 and 5, with frames adapted to guidewaTy's 4" and 5 on the opposite sides of the window frame, these guideways being, by preference, formed in bars or strips. 6 secured to the opposite sides of the-window frame, and the outer screen section 4 being free to slidevertically, independently of the inner section ()neiof the horizontal bars of one of the screeniseetions is provided with a strip or bar 7 for hearing against the adjoining face of the other screen section so as to prevent insects from entering the room or apart-- ment' between the two sections of the screen Le te a e t Patented Sept. 30, 1 9i 3. 1912.

present instance this stop bar is applied to the upper hait ot the inner screen frame but it. may, with ,the lower bar of the desired. I v

The lower member of the sash 2 is provided with lugs or a bar 8, Fig. 3, for engagement with a projecting member 9 on the frame of the outer screen section. When the lower sash is down or only partly raised, the screen sections are also lowered to the position shown in Fig. 1 and occupya osiouter screen frame, if

the same etlect, be applied to.

tit

tion one behind the other, so that the View through the sash pane above the screen sections is not obstructed or obscured. When the lower sash is fully raised, as shown in Fig. 2, the member 8 of the sash en ages with the tnember 9 of the oiiter'sereen name and raises said outer section of the screen in its guideuays so as to completely screen lower sash. \Vhen the sections of the screen are lowered" they do not interfere with the swingingot the sashes in that type of window in which the sashes are ivoted about midway of their length. As tie screens are out of the path of the movingsash they will not prevent the lowering of the latter down the opening formed by the raising of said to the sill, and hence will permit of the locking together of the upper and lower sashes in the usual way.

I claim: y

1. The combination of a window frame and sash with a screen composed of a plu- 'ral i ty of sections. each less in height than the litt htthe sash, means for engaging the outer section with the sash, whereby, as the .latter is raised, it will cause the screen sections to be extended, and guides for said screen sections independent of the guides for the sash, whereby the presence of the screens does not preventthe full closing of the sash.
